Agile Java is a valuable tutorial and reference. It introduces the Java languagewith no assumptions about a developer's background in Java, object-orienteddevelopment, or TDD. The book will also retain significant value as acookbook that readers will turn to time and again to learn how to approachTDD with respect to various language features.Teh author stresses the importance of TDD by showing coded tests for everyJava feature taught. A programmer learning with this book will understand howto translate oral requirements into tests, and tests into working code. Readersalso learn how TDD impacts the design of the system, and vice versa. In short,anyone who wants to understand what it takes to build a professional, robustsoftware system using Java will want this book. Agile Java will be ideally timedto coincide with Sun's forthcoming release of Java 5 (J2SE 1.5).
